SPECIFICATION forming part of Letters Patent No. 783,819, dated February28, 1905.

Application filed November 28, 1904. Serial No. 234,671.

To (all II/7111771, if 'n'z/rt l cone/27w].-

Be it known that 1, James M. CuAMnnns, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Barrel-Heaters, of which the following is a full, clear,and exact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a vertical longitudinal sectional View through abarrel-heater constructed in accordance with my invention. Fig. 2 is across-sectional view on the line 2 2 of Fig. 1, and Fig. 3 is across-sectional view on the line 3 3 of Fig. l.

This invention relates to barrel-heaters, and is 1 )articularly designedfor heating and drying cashs or barrels preparatory to hoopii'ig andfinishing the same.

One of the objects of the invention is to heat the barrel or caskexternally and internally, so as to obviate the necessity andinconvenience of lifting the barrel by hand for placing it around theheater.

Another object of the invention is to pro vide means whereby a maximumheat cliiciency will be generated by a given amount of fuel, so that theproducts of combustion will have an opportunity to generate considerableheat before passing off through the chimney or into the outsideatmosphere when it leaves the heater.

Another object of the invention is to pro vide means whereby a hangingfire-pot or grate may be suspended within the heater in such a mannerthat the draft will pass through the grate from the top and then bedeflected upwardly byasuitable bai'lle, so that the products ofcombustion may act upon the surrounding casing which is to be heated.

Other objects and advantages, as well as the noveldetails ofconstruction of this invention, will be specifically describedhereinafter, it being understood that changes in form, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages thereof.

.ln the preferred form of my invention as illustrated in theaccompai'iyingdrawings I utilize a plurality of stamlards 1, which mayconsist of castings, channel-irons, or any other suitable constructionand which support a drum or sheetiron casing 2. This casing rests on topof a ring 2) on the standards, and upon the upper edge of the drum is acover t, secured to the ring 3 by the tie-rods 5. The cover 4: isprovided with a central opening siu'rounded by a depemling circularflange 6, extending within the casing .2 and having aninwardly-projecting lug '7 at its lower edge, which is in a lower but aparallel plane to the plane of the cover i. it will be seen that the lug7 projects inwardly at a right angle to the llange 6 and constitutes arest to support the hanging li re-pot 8, which is liared dmvnwaudly fromits upper end to a point at its opposite end 9, said lire-pot having adependingcircular baffle 10 integral therewith, the purpose of whichwill be apparent as the construction of the ii'ivention is betterlll'ldOlStOOtl. The lire-pot 8 constitutes a receiver for the fuel, andat its lower end 2) are inwardly-projecting lugs 1.1., divided by spaces12, whereby the outwardly-projecting lugs 13 of the grate 1.4; may becaused to alternate with the lugs 11, and by slightly ro'tatingthe grate14 the lugs 13 will be caused to register with those designated by thenumeral ll, whereby the grate 14 will be hungor suspended from thelire-pot 8. The grate 14L is open at its top and is provided with aplurality of vertical, bars l5 and transverse bottom bars 16, so thatthe draft through the fuel will in no wise be retarded.

Suspended from the flange (3 is a sheet-iron inner casing 1'7, whichentirelysurroimds the lire-pot, grate, and battle and projects below thelower edge of said baitl'le 10. This sheetiron inner casing 17 isprovided at its lower edge with an inwardly1 )rojecting llange 18, theinner edge of which surrounds an opening normally closed by a cover 19,having a lug 20 at one edge thereof and a swn'igmg locking device 21 atthe opposite edge, so that the lug 20 and the locking device 21 may becaused to engage the flange 1.8, so as to support the cover ii) on saidflange.

The top 22 of the heater is bolted or otherwise secured to the cover i,and it is provided with a dependingflange 23, extending within theopening surrounded by the flange 6, the flange 23 being substantiallyparallel with the flange 6 and having outwardly projecting flange 24resting on the upper lug 25 of the lire-pot 8, to which said flange 24cis bolted. It will be observed that the flange 23 is substantially thesame diameter as the entranceopening of the fire-pot 8, so that the fuelwill be conveniently guided into the fire-pot 8, constituting thefuel-receiver, and into the grate.

A swinging cover 26 is pivoted to the top 22 of the heater, whereby theopening 27 may be uncovered for the introduction of fuel or to regulatethe drafts.

In the top 22 and surrounded by the flange 28 is a smoke-opening 29,which communicates with a space 30, formed by the outer walls of thefire-pot 8 and the wall of the casing 17 Between the outer casing 2 andthe inner casing 17 are the vertical rods 31 of the elevating device,including the base or platform 32, supported by said rod, and on whichthe barrel or cask is placed. These rods are connected at their tops bythe cross-bar 33, and

intermediate the ends of the cross-bar is a pulley 34.

From a suitable support 35 is a cord or cable 36, passing around thepulley 34, thence over a pulley 37, and on the end of this cord or cable36 is a counterbalance-weight 38 of about the same weight as the cash orbarrel to be heated.

In operation it is to be assumed that lire is in the grate 1 k and thatthe barrel has been placed upon the platform 32. l he draft will enterthrough the top of the lire-pot, as indicated by the arrows, and passdown through the grate 14 to the bottom of the inner casing 17, where itwill be deflected by the cover 19 and the baffle 10 in an upwarddirection through the space 30 and between the baflie 10 and the innercasing 17 until it passes through the smoke-opening 29. Thus the entireinner casing 1'7 will be heated and will radiate heat into the space 39formed between the inner and outer casings and in which the barrel willrest. The operator may cause the counterbalance-weight 38 to descend andin an obvious manner raise the barrel 40 until it surrounds the innercasing and is in turn surrounded by the outer casing. Thus it will beapparent that the outer and inner walls of the barrel will beefficiently heated preparatory to hooping and finishing.

One of the particular advantages resulting from the constructionhereinabove described is that the downdraft will permit an even heat toradiate from the inner casing of the heater, so that a uniform dryingout will take place from one end of the barrel to the other. Anotheradvantage is that the exterior of the barrel will also be thoroughlydried. When it is desired to rake the grate, this can be readilyaccomplished by removing the cover 19, so that access to the grate 14may be easily had. By suspending the grate as indicated in the drawingsthe grate may be easily removed, as well as the entire fire-pot may betaken out or assembled. The arrangement and construction of the grate issuch that an easy combustion of the fuel is insured and the draft Willbe in no wise retarded. Therefore the maximum efficiency for the devicewill be provided.

Having thus described my invention, What Iclaim, and desire to secure byLetters Patent, is

1. A barrel-heater comprising an inner and outer casing, a hanging gratein the inner casing, and a battle surrounding the grate and extendingnearly to the bottom of the inner casing; substantially as described. I
